What types of molecules have difficulty crossing the plasma membrane?
Large, polar, uncharged molecules cannot pass through a membrane without the help of protein channels embedded into the plasma membrane. Ions also have difficulty passing; they need ATPs.
What is pore protein?
integral protein that embedded to the plasma membrane. Allow small substances to cross the plasma membrane.
The plasma membrane is a thin sheet of lipid embedded with?
protein
How do other molecules pass through the selectively permeable cell membrane?
[Molecules pass through the cell membrane] through a process known as osmosis. ------------------------------------------------------- Yes, osmosis is a great part of diffusion of molecules, but another important factor to consider is the presence of protein channels in the membrane. The cell membrane is actually a lipid bilayer, in which proteins are embedded. Normally, molecules will simply be diffused through these chanells, but in some cases, the protein must be modified in order to allow the molecules to flow. This is called active transport, which requires energy in order to change the shape of the protein and allow the foreign molecule to pass.
What proteins are embedded in the plasma membrane?
They are called integral proteins
Embedded in the phospholipid bilayer?
Protein Molecules

Embedded in the phospholipid bilayer are?
Protein Molecules
What is pore protein?
integral protein that embedded to the plasma membrane. Allow small substances to cross the plasma membrane.
What is aquaporins?
Aquaporins are protein molecules embedded in the phospholipid bilayer (cell membrane ) of some cells. They transport water across the cell membrane.
The plasma membrane is a bilayer of lipid molecules with protein molecues embedded True or False?
it depends on what you are referring to. the lipid bilayer is exactly what it says.it is two layers compsed of lipids. lipid molecules have two properties: a hydophobi tail and a hydrophilic head. so when the bi layer is put together, it has the tails facing eachter and the heads out to react with water conditions in the body. the membrane is also embedded with proteins of all dffierent kinds that allows ions to cross and this allows for cell communication
The plasma membrane is a thin sheet of lipid embedded with?
protein
Why are pores in the cell membrane different sizes?
They selectively allow certain size molecules to enter, or not to enter, the cell.

Whats the function of tethered protein?
A tethered protein is one that is not embedded inside a membrane but is suspended away from it.
What are the molecules that give the cell membrane a mosaic structure?
protein molecules in the cell membrane gives the mosaic structure .
